DRK835A fabric surface friction coefficient tester (Method A) is suitable for testing the friction performance of fabric surface. Standards compliant: FZ/T01054-2012 Method A and other standards. Features: 1. Color touch screen, Chinese and English with single operation interface. 2. The system accessories all adopt high-performance imported components, with stable and reliable performance. 3. The friction coefficient function is provided, and three test modes of dynamic friction, static friction, and dynamic and static friction are available for users to choose freely. 4. The core control components are 32-bit multi-function motherboards from STMicroelectronics. 5. The instrument test bench and the test slide have been demagnetized and tested for remanence, which effectively reduces the system test error. 6. Professional software can automatically perform statistical analysis of the results of single and group tests, re-analysis of original data, group curve overlay comparison, and multiple report modes to intuitively and quickly display test results to customers. 7. Equipped with a micro printer and a standard RS232 interface to facilitate the external connection and data transmission between the system and the computer. Technical parameter: 1.
